Philosophy in midst of Argument

as we argue forcefully my antagonist & i
suddenly mused me " why? why? why ??????"
one day we shall both turn to dust
arguin' in anger , begotten by lust
to win the argument win, win win
to any depth both can sink --sin, sin , sin
one day none of us will be here---
the Solar Milky way too will go so
Harken my dear
by losin' an argument we might lose face
but we are just 2 future dead bodies
futilely interactin' in Interstellar Space .....!
